Secrets to successful investing
Navigating stock market downturns
Market Volatility explained
What's happened?
Shares of technology companies have fallen sharply in the US and Asia as investors question how quickly artificial intelligence (AI) can continue to grow. The falls followed the US midterm elections, where some candidates called for limits on new AI data centres – the buildings that house the computers needed to run AI.
European shares have also fallen, though less sharply than those in the US and Asia. Share prices have also fallen in other types of business, including retailers and healthcare companies.
This means the effects could reach a wider range of investments, not just those focused on AI. It’s too early to know how long these falls might last or whether markets could fall further.
The key thing to remember is that the effects of these events are usually short-lived. Markets usually recover fairly quickly.
Investing should be for the longer term which can help ride out any of these short-term ups and downs in value.
What to think about
What this might mean for you
News headlines can feel unsettling, but short‑term volatility is a normal part of investing. Markets have been through similar periods many times and usually adapt or recover quickly.
Reacting to every movement can introduce more risk and uncertainty into your own plan. Sticking to a long‑term approach helps you avoid decisions that could result in losses.
If you’re unsure what’s right for you, an independent financial adviser can help.
Investing for longer increases the likelihood of positive returns. Over a period of 5 years or more, investments usually give you a higher return compared to cash savings. But investments can go down as well as up in value, so you could get back less than you put in.

This chart shows the S&P World Index (GBP) from 1995 to 2025. The index starts at about £125 in 1995 and ends just above £930 in 2025. Over these 30 years, the index generally rises, but there are several periods where it falls due to global events.
Key events and their impact
- 1999 to 2003: The index climbs quickly, then drops to around £200. This change is linked to the dot-com bubble, the 9/11 attacks and conflict in the Middle East.
- 2007 to 2009: The global financial crisis causes the index to fall sharply after reaching about £400.
- 2015: Growth slows but stays positive. This is due to a slowdown in China, the Greek debt crisis and lower petrol prices.
- 2020: The Covid-19 pandemic leads to a clear dip after a period of steady growth.
- 2022: The index moves up and down but keeps rising overall. This period includes the Ukraine war, higher inflation and rising interest rates.
- 2025: The index peaks near £1,200, then drops below £1,000. This is linked to new US tariffs.
Summary:
The S&P World Index (GBP) shows long-term growth from 1995 to 2025, with several short-term declines caused by major world events.
